Can you provide an example from the scriptures of how unwavering faith led to a divine vision for a devotee of Sai Baba?

A prime example of faith leading to a divine vision is the experience of Kakasaheb Dixit. As recounted in chapter 4, while Kakasaheb was in meditation after his morning bath, he received a vision of Vitthal. Later that day, when he went for Baba's darshan, Baba confirmed the vision by asking, "Vitthal Patil had come, right? Did you meet him?" Baba further advised him to hold onto that vision firmly, warning that Vitthal is a "big runaway" and will disappear with even a moment of neglect. This incident was further validated when a seller arrived with pictures of Vitthal, one of which was an exact replica of the form Kakasaheb had seen. This story powerfully demonstrates how a devotee's focused faith can manifest in a direct, verifiable experience of the divine.
